论文摘要
大型高海拔空气淋浴天文台（Lhaaso）正在中国四川的Haizi Mountain建造，高度为4410 m。它的主要目标之一是通过其基于地面的水Cherenkov检测器阵列（WCDA）对北方天空进行高度能源（高于100 GEV）的伽玛射线源。 WCDA的尺寸为78000 $ m^2 $，由3120个水池组成3120个水池。从北京Hamamatsu Photon Techniques Inc.（BHP）中安装了一个半球8英寸光电倍增管（PMT）CR365-02-1（BHP），位于第一个水池的每个单元的底部中心，以收集由空气淋浴粒子交叉水的Cherenkov光。该程序包括WCDA的技术设计，CR365-02-1的高动态范围基础的设计，PMT测试系统和997 PMT的测试结果。
The Large High-Altitude Air Shower Observatory (LHAASO) is being built at Haizi mountain, Sichuan, China at an altitude of 4410 m. One of its main goals is to survey the northern sky for very-high-energy (above 100 GeV) gamma ray sources via its ground-based Water Cherenkov Detector Array (WCDA). WCDA is 78000 $m^2$ in dimension and consists of 3120 water detector cells divided into 3 water ponds. A hemispherical 8-inch photomultiplier tube (PMT) CR365-02-1 from Beijing Hamamatsu Photon Techniques INC. (BHP) is installed at the bottom-center of each cell of the first water pond to collect Cherenkov light produced by air shower particles crossing water. This proceeding includes the technical design of WCDA, the design of a high dynamic range base for CR365-02-1, the PMT test system and test results of 997 PMTs.
